  1. Switch off the device

    1. Before your start the repair, switch off your device by holding down the standby button until the shutdown dialog appears on the screen.
    2. Tap to switch off the device.
  2. Remove back cover

    P8 lite (2017) - Remove back cover 05

    Now you can start and remove the back cover.

    It's better to heat the back cover several times if you feel resistance, instead of breaking it.Never insert the tool more than 5 mm. Also don't use the tool as a lever, but run it flatly along the edges to release the glue.

    1. First heat the glue around the edges with a hot air tool to about 60°C. Repeat and heat the back cover to the point where you can barely touch it.
    2. Then slide a very thin, flat tool like the iFlex between the back cover and the frame and slide it around the edge to release one corner of the back cover.
    3. Then slide in a pick. You can use other picks to get off the back cover all around. Don't insert any tool more than 5 mm!
    4. Slide the iFlex around the edges and detach the glue everywhere.
    5. When the glue is detached everywhere, you can lift the back cover off. Carefully open the device, as there is still one flex cable attached.
  3. Disconnect the battery

    1. Apply the hot air from the display side.
    2. We recommend running a flat tool, such as the iPlastix, all around the battery.
    3. Now take out the battery.
    Be careful not to damage the battery. Take your time and heat the glue several times.
